Nemipteridae (Threadfin breams, Whiptail breams)
Etymology: Scolopsis: Name from the Greek masculine noun 'skolos' meaning 'thorn' and suffix '-opsis' (from Greek feminine n. 'opsis' meaning 'aspect', 'appearance') meaning ‘thorny appearance’ presumably referring to 'les dentelures de la préopercule, en ont aussi, et même d'épineuses, aux sous-orbitaires' mentioned by Cuvier (1814) in his designation of the genus. Name ending in -'opsis' are treated as feminine according to ICZN 1999: Article 30.1.2 (Ref. 130620).
